commit-graph: clean up chains after flattened write
If we write a commit-graph file without the split option, then we write to $OBJDIR/info/commit-graph and start to ignore the chains in $OBJDIR/info/commit-graphs/. Unlink the commit-graph-chain file and expire the graph-{hash}.graph files in $OBJDIR/info/commit-graphs/ during every write.
